Claims.

My invention relates to a grease dispensing device and more particularly to a device for dispensing grease from containers.

Currently, it is thecustom to pack greases in 5 cans. Various parts of automobiles are designed to be lubricated with various lubricants and greases. Due to the large variety of greases employed, they are packed in individual containers or cans. A special grease is supplied for packing ball bearings and roller bearings. These are difiicult to pack with grease and, when packed by hand, much grease is wasted.

One object of my invention is to provide a dis pausing device for dispensing grease from conta. rs.

:LuOthGIf object of my invention is to provide a device for packing bearings with grease.

Other and further objects of my invention will appear from the following description.

In the accompanying drawing which forms part of the instant specification and-is to be read in conjunction therewith, and in which like reference numerals are used to indicate like parts in the various views;

Figure lis an elevation of my grease dispensing device with a grease container in grease dispensing position.

Figure 2 is a sectional elevation along the line 22 of Figure 1.

39 Figure 3 is a sectional view taken along the line 33 of Figure 2.

In general, my invention contemplates the provision of a piston provided with a hollow piston rod. Th'e'piston is adapted to fit in a can of grease. The piston rod is slidably supported in a bearing secured to a stand. The upper portion of the stand is provided with a pressure exerting means adapted to push the can of grease against the piston. The piston rod is hollow so that Q greast will flow outthrough the piston rod. The

bottom of the standard is provided with ,a support for the bearing to be packedfiin conjunction with which piston rod extension nembers are provided for use with various sized bearings being 5 packed. v

More particularly referring now to the drawing, a standard i isformedwith a base 2 on which is mounted a seat 3 adapted to support a bearing d which is to be packed with grease. {in arm 5 D carries a hearing 6 in which a hollow piston rod 7 is adapted to slide. The lower end of the piston rod 5 is adapted to receive a bushing 27 in which bushing a mushroom to slide. The mushroom ;member comprises a s stem 28 of an external diameter fitted to the inshaped member is adapted ternal diameter of the bushing 21 and a head 29 which is fiat on top and sloped on the bottom as can readilybe seen by reference to Figure 2.

A .plurality of mushroom members are supplied,

depending upon the packed. The lower end of the piston rod 1 is also provided with a star shaped contact flange 8 to enable observation of smaller sized bearings. The upper end of the'piston rod 1 carries a piston 9. Between the bearing 6 and the piston 8 I 10 provide a spring 26 holding the piston in its uppermost position when the device is not in use. Secured to-the piston 3 by means of plate i0 and screws H is a packing member it. which is size of the bearing to be 5 adapted to seal against the interior walls of the i5 grease container i3 which-is filled with grease it. The screws H are longer than necessary and are provided with sharp projecting ends 22 adapted to pierce the bottom of the grease container 43 when the grease has been exhausted. This prevents further use of the can and also provides vents enabling ready removal of the empty can. The upper endpf standard I is provided with a bore in which is journalled a shaft i5. Secured, tothe shaft 15 is a pinion 85 adapted to mesh with a r'ack H. The rack is mounted for longitudinal movement with the standard i and carries a flange I8 at its lower end. The under side of the -ilange i8 is provided with an annular groove 23 of suflicient depth and in such a position as to enable projections 22 to -puncture the bottom of the can 83. A nut it prevents movement of the shaft l5 out of the standard journal. A plurality of operating arms 29 are provided for rotating the rack ii is provided with a groove 26. A spring. pressed ball 25 is provided in the standard, adapted to act as a detent by engagement with groove at to hold the rack in the upper position enabling the insertion of anew can of grease conveniently; In operation, therack H is raised with spring pressed ball. ZS-engaging groove 2t.

A can of grease is opened and inverted overthe piston 9 and manually pressed downward'y by shaft 15. The

hand 'to start the grease through the hollow 'piston rod.

Theoperating arms 20 are then operated to move the rack downwardly to permit flange plate. It to engage the bottom of the can, the spring- 26 holdingthe assembly in the uppermost posi- 5o tion. A proper sized mushroom is taken. depending upon theparticular size of bearing to be packed. The mushroom stem 28 is inserted upwardly through the bearing with the projecting end of the inner race of the bearing upwardly.

' sub-combinations.

The stem 28 isinserted in the bushing. The rack operating handles are then operated to lower thepiston until star shaped contact flange 8 makes contact with the projecting end of the inner race. Continued movement of the rack will force the can of grease against the piston, forcing grease downwardly through the hollow piston, downwardly through the hollow,mushroom stem between the seat '3 and the mushroom flange, upwardly through the passages between the retainer and the inner race. The diameter of the mushroom flange is such that grease will not flow through the bore of the bearing.

When all the grease in the can has been consumed, the projections 22 will'pierce the bottom of the can, permitting easy withdrawal of the can.

The grease, in passing between the retainer and -the inner race, pushes the old lubricant ahead, thus effectually cleaning the bearing of old grease. At the same time, all the interstices between the balls or rollers and all passages are completely filled with new, clean lubricant. Upon removal of the inner race of the retainer assembly, the bearing is ready to be reassembled and placed in operation.

It will be seen that I have accomplished the objects of my invention. I have provided a novel grease dispensing device which is adapted to be used for packing of ball roller bearings with grease in a simple and expeditious manner.

It will be understood that-certain features and subcombinations are of utility and may be employed without reference to other features and This is contemplated by and is within the scope of my claims. obvious that various changes may be made in details within the scope of my claims without departing from the, spirit of my invention. It is, therefore, to beunderstood that my invention is not to be limited'to the specific details shown and described.
